Leadership

Argonne integrates world-class science, engineering, and user facilities to deliver innovative research and technologies. We create new knowledge that addresses the scientific and societal needs of our nation.

Peter B. Littlewood is the Director of Argonne National Laboratory, one of the nation’s largest science and engineering research centers, and a Professor of Physics in the James Franck Institute at the University of Chicago. Dr. Littlewood came to Argonne in 2011 after being appointed Associate Laboratory Director of Argonne's Physical Sciences and Engineering directorate, which focuses on discovery science across a broad range of disciplines, and on creating and understanding new materials and chemistries that address the grand challenges in energy and the environment.

Alfred P. Sattelberger is the Deputy Laboratory Director for Programs, Chief Research Officer, and Senior Intelligence Official at Argonne National Laboratory. He is responsible for managing the interactions of Argonne’s scientific programs with federal, state, and local stakeholders, including DOE and other sponsors, and for building relationships with other national laboratories, the university community, and international collaborators that enable new groundbreaking research and large-scale programs.

Matthew Tirrell is Deputy Laboratory Director for Science at Argonne National Laboratory. He is responsible for integrating the laboratory’s research and development efforts and science and technology capabilities. He develops and drives strategy to support integrated teams across disciplines in support of Argonne’s strategic initiatives.

Paul K. Kearns is Deputy Laboratory Director for Operations and Chief Operations Officer for the U.S. Department of Energy's Argonne National Laboratory. He brings nearly three decades of management experience to the position, as well as a strong background in science and engineering.

Jeffrey L. Binder is the Associate Laboratory Director of Argonne National Laboratory’s Energy and Global Security (EGS) Directorate, a team that applies unique expertise in science, engineering and information systems to deliver environmentally sound solutions to challenges in energy access and global security.

Rick Stevens is Associate Laboratory Director for Computing, Environment and Life Sciences. Stevens oversees a research program that connects computing to several areas of inquiry, and heads Argonne's research initiatives for both exascale computing and computational biology. He is a professor in the Department of Computer Science at the University of Chicago, a Senior Fellow of the Computation Institute, and a Senior Fellow of the Institute for Genomics and Systems Biology.

Stephen Streiffer is the Associate Laboratory Director for Photon Sciences at Argonne. Photon Sciences consists of the X-ray Science, Accelerator Systems and Advanced Photon Source Engineering Support divisions, which comprise the Advanced Photon Source (APS), the largest scientific user facility in North America; and the Argonne Accelerator Institute.

Harry Weerts is the Associate Laboratory Director for Physical Sciences and Engineering. He oversees Argonne’s interdisciplinary research programs in physics, chemistry, material science and nanotechnology. Weerts was formerly Director of Argonne’s High Energy Physics division, and prior to that, a collider physicist at Fermilab, where he was the spokesman for the Dzero experiment for six years.
